Hi all, |
2 |
I'm having all sorts of trouble getting a new computer to boot. I have |
3 |
two NVME thingies in it with one containing Win10 and the other, |
4 |
eventually, Gentoo. I use Refind to control the booting with the machine |
5 |
using UEFI. |
6 |
|
7 |
The graphical front end to Refind boots fine and allows me to in turn |
8 |
boot Windows. It also spots and then allows me to boot a copy of |
9 |
SysrescueCD that I left plugged in. No joy with Linux. I get up to where |
10 |
the kernel appears to be doing something with sata and then it crashes. |
11 |
Now herein lies the problem. |
12 |
|
13 |
Is there a way to get dmesg logged to a file so that I can see what's |
14 |
actually failing? I need to be able to get back into the machine with |
15 |
SysrescueCD, which is no problem, and then have a look at the dmesg |
16 |
output to see what's going wrong. |
17 |
|
18 |
Does anyone have any idea as to how to do this, or another way of doing |
19 |
the debugging I'm trying to do? The stuff I've found on the web assumes |
20 |
that some of the loggers are working and can do stuff, I'm not getting |
21 |
to the stage where they have started up yet. |
22 |
|
23 |
I'm in the process of transferring from a non EFI hard disk setup to |
24 |
EFI & nvme. The hard disk based system boots with no problems. Assuming |
25 |
that the hard disk system and the nvme system will give nearly the same |
26 |
dmesg, looking at the hard disk dmesg, I see that if I go to where I |
27 |
think is the same posi as the crash on the nvme, is where it attempts to |
28 |
mount root: |
29 |
|
30 |
VFS: Mounted root (jfs filesystem) readonly on device 8:19. |
31 |
|
32 |
If I have managed to do something wrong with respect to this mounting, |
33 |
would it cause the crash or just complain and freeze? |
34 |
|
35 |
Any thoughts on this would be greatly appreciated, |
36 |
